Have been flipping some A Level bio textbook like hell, but found nothing useful to answer alfagal's question. What a hard one.Originally posted by renorenal:Hahaha... I think it's Purkinje fibers... If I am not wrong... Ahhh... never mind... going to sleep d... goodbye! -

SPECIAL MYSTERY QUESTION
Why is it that:
When you look at the rose in the day, the petals will look redder than in the evening.
Now, when you look at the same rose again in evening time, the stalk appears greener than in the day.
What is the name of this phenomenon?
--------------------------------------------------------------------------------
yup this qn is abit hard, needs a lil more research.
CLUE 1: the phenomenon starts with letter 'P'
CLUE 2: the name of this phenomenon coincides with a neuron name in the cerebellum.
Yes reno got it right. (you can ask for anything you wan!
)
Explanation:
Basically, i am jus looking for the name of the phenomenon
The phenomenon is the Purkinje Shift.
Cones are divided mainly into S M L. Sensitive to Short, Medium and Long wavelengths (colors: Blue, Green and Red respectively).
In the day, the L cones are more sensitive than the M & S, and in the evening time, the S are more sensitive than the M & L cones, therefore a rose would appear redder in the day and the stalk would appear greener in the evening even though its the same rose.
During night time, we depend on our rods (detects edges, outlines, monochromatic vision) more than cones (detects colours, details),unless you are in a brightly lit area all the time.
Interestingly, we can assume that the amount of activity shifts from L to S cones during day to evening, hence the Purkinje Shift, then at night the rods come into play.
Point to ponder:
Some of you might have come across, or experienced them yourself esp if you are a driver:
Why do they complain every road appears the same at night! but in the day, it seems alright (so its okie to get lost)
Or:
How come some places appear different during the day and night?
You will know whats the reason why now.
Anyway:
